Bridge assembly type handrail special for pedestrian overcrossings and bicycles

Abstract

The invention discloses a bridge assembly type handrail special for pedestrian overcrossings and bicycles. The handrail comprises a plurality of pouring aluminum stand columns parallel to one anotherand perforated aluminum plate breast boards arranged between every two adjacent pouring aluminum stand columns, a stainless steel anti-collision steel pipe and an extruded aluminum handrail are arranged between every two adjacent pouring aluminum stand columns at the inner side of the handrail, and the handrails are arranged at the two sides of a bridge. Each pouring aluminum stand column comprises a fixing rod slightly inclining towards the outer side of the bridge and a guide rod arranged at the lower end of the fixing rod and bent downwards along a bridge flange, and lugs are arranged at the inner sides of the upper ends and the middles of the pouring aluminum stand columns. The upper ends and the middles of every two adjacent pouring aluminum stand columns are each provided with a horizontal stainless steel anti-collision steel pipe, the two ends of each stainless steel anti-collision steel pipe are fixed to the lugs of the corresponding pouring aluminum stand column through the connecting pieces respectively, and the extruded aluminum handrail is arranged between the stainless steel anti-collision steel pipes at the upper end and the middle of the pouring aluminum stand column. The handrail is good in practicability, is durable, economical, attractive, is convenient to maintain in the later period and is high in replacement efficiency.

Description

technical field [0001] The invention belongs to the technical field of pedestrian bridges and special bridges for bicycles, in particular to an assembled railing for pedestrian bridges and special bridges for bicycles. Background technique [0002] At present, most pedestrian bridges use steel or stainless steel railings. The railings are pre-embedded in the concrete floor, which has a single form and occupies the clear width of the bridge deck. It is convenient to set up the lighting system on the bridge. [0003] When the railings are seriously corroded or damaged, they can only be repaired by cutting off the original columns and welding new columns on site. In severe cases, it is even necessary to remove the ground and railings as a whole, re-pour the ground concrete and install the railings. The construction period is long and the quality is high. Difficult to guarantee. [0004] Under the general environment of "co-construction and sharing, and the health of the whole...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an assembled railing for pedestrian bridges and bridges dedicated to bicycles. Its purpose is to solve the problem that the steel railings used in existing pedestrian bridges have a single form, occupy the clear width of the bridge deck, are not beautiful and are not convenient to install lighting systems. The on-site welding effect is difficult to guarantee and the efficiency of later maintenance and replacement is low
